Plasma cutting machine uses the high-speed airflow ejected from the nozzle to ionize to form an electrical conductor. When the current passes through, the conductor forms a high-temperature plasma arc. The heat of the arc partially melts the metal at the incision of the workpiece. A process in which molten metal is removed to form an incision. The slender and stable plasma arc formed by the annular gas flow technology can ensure smooth and economical cutting of any conductive metal. It is easy to understand after knowing the working principle of the high-power plasma cutting machine and then learning the precautions for operation.
First of all, cut from the edge, do not pierce the cut. Aim the nozzle directly at the edge of the workpiece before initiating the plasma arc, using the edge as the starting point to extend the life of the consumable. The nozzle and electrode are consumed very quickly when starting the arc, so be sure to place the torch within the walking distance of the cutting metal before starting to reduce unnecessary arc starting time.
Secondly, don’t overload the nozzle. If the load is exceeded, the nozzle is more likely to be damaged. Generally, the current intensity is 95% of the working current of the nozzle. The distance between the cutting nozzle and the surface of the workpiece should be reasonable. Generally, it is more appropriate to use twice the normal cutting distance, or the maximum height that the plasma arc can transmit.
The thickness of the perforation must be within the range specified by the high-power plasma cutting machine. If it exceeds the specified cutting thickness, the desired cutting effect cannot be achieved. Usually, the perforation thickness is 1/2 of the normal cutting thickness. When replacing consumable parts, clean up the dust and dirt on the surface to keep the surface of consumable parts clean. Also check the link thread of the torch frequently, and clean the electrode contact surface and nozzle with a hydrogen peroxide-based cleaner.
Only the correct operation of the high-power plasma cutting machine can ensure the normal operation of the equipment and high-quality and efficient work. In the next section, the editor will introduce the relationship between cutting speed and cutting quality of high-power plasma cutting machines.
